I have labelled this release as beta, because the code to upgrade from the previous major release (0.62) is missing. Though, this is probably unfair since this version is already being used in production, and it is recommended to use it for new projects.

i am curious to know why you chose to remove the multi-site feature as it seems that most CMS’s and E-commerce shops are re-writing their code to have exactly this feature, for example drupal-multi sites or the new version of prestashop 1.5

another cool thing would be to be able to have a remote storage based on a per folder, like for example on github, when you create a repository, in this case a folder becomes a repository and you can choose where you want to store this.

The multi-site feature added too much complexity. The idea is to get it back in a different form: to have a web application where you can add new sites, but where each site is an independent ikaaro instance.
